SEOUL, South Korea--(BUSINESS WIRE)--15 years after it began the development of chassis technology, Hyundai
Mobis (KRX:012330) finally succeeded in securing world-class
technology in the car suspension system, following advances in braking
and steering. With this new technology, the automotive supplier has been
able to deliver optimal performance by integrating all chassis functions
and improve the safety of automotive driving systems by raising control
precision.

Hyundai Mobis announced on the 24th that it had recently
developed eARS (electrical Active Roll Stabilization), an electronic
controlled suspension component.

eARS is an auto component used to stabilize the horizontal inclination
of the body of a running vehicle by mitigating the leaning of the body
caused by centrifugal force when the car turns quickly and the impact
from irregular surfaces. While the stabilizer bar, the former technology
of eARS, compromises the comfort of the ride when the car is running
forward to raise cornering performance, this new technology can actively
respond to both situations.

Developed by Hyundai Mobis over the past five years, eARS delivers
world-class performance, increasing body stabilization performance by
40% and reducing the size of the system by 5% compared to the
specifications of global competitors. eARS was developed based on 12V
and 48V, making it suitable for green vehicles. Hyundai Mobis is the
only Korean automotive supplier to have developed eARS based on both 12V
and 48V.

Hyundai Mobis' eARS employs the next generation electric motor control
method, which replaces traditional hydraulic control methods, and the
new technology is currently produced by only a few automotive suppliers
from Europe and Japan. Due to its high price, eARS has been applied to
limited premium models. The development of an economical version of eARS
is expected to usher in a period of almost limitless growth. Hyundai
Mobis is currently developing an economic version of its eARS by
employing only the core features of the technology.

With the development of eARS, Hyundai Mobis could secure its own
electrification technology in chassis, following ones in braking and
steering. This new development represents the culmination of the past 15
years of research by Hyundai Mobis into developing electrification
technology instead of traditional hydraulic technology, applying
electronics to mechanical components.

Last year Hyundai Mobis supplied high performance electric steering
systems, which surpassed European ones, to premium models. More
recently, it has applied the integrated electric regenerative braking
system that it developed for the second time in the world to FCEVs,
thereby becoming the world's first automotive supplier to apply the
technology to green vehicles. The automotive supplier also started to
mass-produce 4-wheel electronic air suspension in 2012 for the first
time among the domestic players.

"Based on our new world-class electric chassis technology, we are
planning to improve the safety of autonomous driving systems by applying
our own sensors such as radar, lidar and camera to them," said Kim
Se-il, Sr. Vice President of Hyundai Mobis Chassis & Trim.
